reset value.
[14]
WKINT
UART Wake-up Interrupt Indicator (Read Only)
This bit is set
if WKIEN (UART_INTEN[6]) and WKIF (UART_INTSTS[6]) are both set to
1.
0 = No UART wake-up interrupt is generated.
1 = UART wake-up interrupt is generated.
[13]
BUFERRINT
Buffer Error Interrupt Indicator (Read Only)
This bit is set if BUFERRIEN(UART_INTEN[5]) and BUFERRIF(UART_ INTSTS[5]) are
both set to 1.
0 = No buffer error interrupt is generated.
1 = Buffer error interrupt is generated.
[12]
RXTOINT
RX Time-out Interrupt Indicator (Read Only)
This bit is set if RXTOIEN (UART_INTEN[4]) and RXTOIF(UART_INTSTS[4]) are both set
to 1.
0 = No RX time-out interrupt is generated.
1 = RX time-out interrupt is generated.
[11]
MODEMINT
MODEM Status Interrupt Indicator (Read Only)
This bit is set if MODEMIEN(UART_INTEN[3]) and MODEMIF(UART_INTSTS[3]) are both
set to 1
0 = No Modem interrupt is generated.
1 = Modem interrupt is generated..
[10]
RLSINT
Receive Line Status Interrupt Indicator (Read Only)
This bit is set if RLSIEN (UART_INTEN[2]) and RLSIF(UART_INTSTS[2]) are both set to
1.
0 = No RLS interrupt is generated.
1 = RLS interrupt is generated.
[9]
THREINT
Transmit Holding Register Empty Interrupt Indicator (Read Only)
This bit is set if THREIEN (UART_INTEN[1]) and THREIF(UART_INTSTS[1]) are both set
to 1.
0 = No THRE interrupt is generated.
1 = THRE interrupt is generated.
[8]
RDAINT
Receive Data Available Interrupt Indicator (Read Only)
This bit is set if RDAIEN (UART_INTEN[0]) and RDAIF (UART_INTSTS[0]) are both set to
1.
0 = No RDA interrupt is generated.
1 = RDA interrupt is generated.
[7]
Reserved
Reserved. Any values read should be ignored. When writing to this field always write with
reset value.
[6]
WKIF
UART Wake-up Interrupt Flag (Read Only)
This bit is set
when TOUTWKF (UART_WKSTS[4]), RS485WKF (UART_WKSTS[3]),
RFRTWKF (UART_WKSTS[2]), DATWKF (UART_WKSTS[1]) or
CTSWKF(UART_WKSTS[0]) is set to 1.
0 = No UART wake-up interrupt flag is generated.
1 = UART wake-up interrupt flag is generated.
Note:
This bit is cleared if all of TOUTWKF, RS485WKF, RFRTWKF, DATWKF and
CTSWKF are cleared to 0 by writing 1 to the corresponding interrupt flag.
[5]
BUFERRIF
Buffer Error Interrupt Flag (Read Only)
This bit is set when the TX FIFO or RX FIFO overflows (TXOVIF (UART_FIFOSTS[24]) or
